I'm wondering if there is a fix for this in the works? Is there a workaround? It's annoying that every time I import a Powerpoint, I must go back through and select each individual, originally 'clear', PPT text box, shape, and group, and then select 'No fill'. There was no fill in PPT--why is it added on import?
Another common import issue is that text boxes are resized--something about the sizing, margins, or line spacing changes on import.
